I am using the supplied Synergistic Research Purple fuse.  Anyone here try the newer SR Master fuse with their Signature Rendu SE?  If so which fuse was preferred?  Thanks for any details!

Update:  Sonore VP has tried the Synergistic Master Fuse, and reports it does result in an improvement.  As always, I am hesitant to recommend it due to the very high price-but if everything else in your system is "perfected", perhaps a Master fuse is what you need to gain that last little bit of sonic bliss.  Sonore will offer the Master Fuse as a special order option for the Signature.  Please note that it is unlikely that we would stock these fuses due to the cost, but we will special order them for new Signature builds if requested.

I ordered the new Signature Rendu SE optical v3 the other day. Looking forward to sharing my sonic impressions of this new update.

Yours is almost built, just waiting on our capacitor order to arrive from Germany, FedEx mis-sorted the package...If all goes well, it will ship on Monday before I take a little break here.

Is it possible to have a better description of the improvements of this new Signature SE D ?

https://sonore.us/Signature-Rendu-SE.html

My understanding is this unit is a normal opticalRendu + @barrows PS design. 
 

Has the opticalRendu changed lately, and what is those differences to previous version ?

Is it only a better PS design that applies ?

 

 

I am not sure of the question, but here is the news on Signature Rendu deluxe

Completely new main board, with a new, better, switch chip, much improved clock distribution circuit, and various other small improvements.  The power supply improvements include new refinements in the transformer secondary damping circuit, and the final decoupling filter before the discrete regulator circuit.

Generally speaking, the Signature Rendu is the flagship product of Sonore.  The Signature includes a very high quality, made in the US chassis, which results in much better control of vibrations, it includes a no compromise power supply design using the best parts available, including a custom built, made in the US, transformer designed specifically for this product, and a discrete regulator circuit which performs at a lower noise level and lower output impedance than any IC based circuits can.  Internally, the AC side of the product (AC input wiring, filtering, and transformer) is shielded for both RF and EM from the signal processing and DC power side of the component.

The Signature Rendu is designed to achieve the best possible performance without concern for compromise regarding parts quality costs, etc.  Each unit is hand built and tested one at a time here in the US.

Is this the same main board as in the latest https://sonore.us/opticalRendu.html ?

 

Yes, the main board is new in both the oR and the Signature (Deluxe versions), and it is nearly identical in both.  The performance is quite different though due to the power supply in the Signature and the fact that it has a real chassis (think vibration control and lower processor temperature) and the close coupling between the power supply and the main board: digital products perform best with ultra low power supply impedance, and external supplies make this almost impossible to achieve due to the impedance of the connecting cable between devices and the connectors themselves.
